Abstract

SE DESCRIBE UN DISPOSITIVO Y UN METODO PARA EL DIAGNOSTICO CONTINUO DE LA UNIDAD DE INDUCCION FORZADA DE UN MOTOR DE COMBUSTION INTERNA POR INDUCCION FORZADA (2). EL DISPOSITIVO (1) ESTA CONECTADO A SENSORES (6) Y (7) QUE MIDEN LA PRESION DE ENTRADA (TIP) Y LA PRESION DE SALIDA (TOP) DEL TURBOCOMPRESOR (4) Y DETERMINA SU PROPORCION ACTUAL; ADICIONALMENTE, ESTA CONECTADO A UN DISPOSITIVO PARA LA DETERMINACION DEL CONSUMO (8) QUE CALCULA EL CONSUMO DE COMBUSTIBLE (FC) Y A UN SENSOR (3) PARA EL NUMERO DE REVOLUCIONES (NER) DEL MOTOR (2) Y DETERMINA LA PROPORCION TEORICA MINIMA SEGUN EL CONSUMO DE COMBUSTIBLE CONSEGUIDO Y EL NUMERO DE REVOLUCIONES. LA PROPORCION ACTUAL SE COMPARA ENTONCES CON LA PROPORCION MINIMA TEORICA Y, SIEMPRE QUE ESTA POR DEBAJO DE ESTA PROPORCION, SE GENERA UNA SEÑAL DE ALARMA A TRAVES DE UN DISPOSITIVO ADECUADO (13).A DEVICE AND METHOD FOR THE CONTINUOUS DIAGNOSIS OF THE FORCED INDUCTION UNIT OF AN INTERNAL COMBUSTION ENGINE BY FORCED INDUCTION IS DESCRIBED (2). THE DEVICE (1) IS CONNECTED TO SENSORS (6) AND (7) THAT MEASURE THE INLET PRESSURE (TIP) AND THE OUTLET PRESSURE (TOP) OF THE TURBOCHARGER (4) AND DETERMINE ITS CURRENT PROPORTION; ADDITIONALLY, IT IS CONNECTED TO A DEVICE FOR THE DETERMINATION OF CONSUMPTION (8) THAT CALCULATES THE FUEL CONSUMPTION (FC) AND A SENSOR (3) FOR THE NUMBER OF REVOLUTIONS (NER) OF THE ENGINE (2) AND DETERMINES THE MINIMUM THEORETICAL PROPORTION ACCORDING TO THE CONSUMPTION OF FUEL OBTAINED AND THE NUMBER OF REVOLUTIONS. THE CURRENT PROPORTION IS THEN COMPARED WITH THE THEORETICAL MINIMUM PROPORTION AND, ALWAYS THAT IT IS BELOW THIS PROPORTION, AN ALARM SIGNAL IS GENERATED THROUGH A SUITABLE DEVICE (13).
